China has urged the United States to revoke a recent resolution reaffirming the Taiwan Relations Act and the Six Assurances as the cornerstone of U.S.-Taiwan relations.

The U.S. House of Representatives passed the Concurrent Resolution on Monday.

In 1982, the then-U.S. President Ronald Reagan issued the Six Assurances, which stipulated that the United States would not "formally recognize Chinese sovereignty over Taiwan."

Foreign Ministry spokesperson Hong Lei said at a routine news briefing that the United States should take effective measures to eliminate the negative effects of the Concurrent Resolution.

He also expressed China's firm opposition to it:

"Taiwan affairs fall totally within China's domestic affairs. The Taiwan Relations Act, among other promises that are passed by the US, violate the three Sino-US joint communiques and the one-China policy. China always firmly opposes intervention in China's domestic affairs. China opposes the relevant resolution passed by the US House of Representatives."

He urged the United States to abide by the commitment to oppose "Taiwan independence."
